I have designed a nice and very strong roof rack that sits low and bolts directly to the roof. It easily bolts together, which makes shipping easy. It is going through the testing phase and will be available soon if all goes well. At the moment the side rails only are available. Feel free to post any questions on it or send a pm. Both are priced with shipping INCLUDED. Racks are 300 and side bars are 135.
First test: 232lbs of steel tube up there.
What the bolted connections look like. I will be including allen head set screws instead of those socket screws.
Note: some pics show partial welds for fitment test, the racks will be fully welded at the connection points.
Side rails

Is there much difference between these and the RRO ones? Thicker or stronger somehow? My RRO's went on fine, seems the biggest problem with aftermarket rails on the Liberty is just the mounting points. Love your products though ATH, not trying to offend by comparing to the RRO rails, I've heard many people don't like them haha. Keep up the good work!

PS have you tried making any vertical extensions for a rack to fit and function with a skyslider? Or has anyone tried this?

I don't know the specs on the rro bars, but mine come with precisely measured round holes instead of slots.

The specs on mine are:
1.32" x 0.133" structural A500 tubing with 1/4" thick feet.
The rise is about 3.75" to the top, 2.43" to the bottom. The actual distance between the roof and they side rails is variable because the roof is curved, but its about 2" in the middle.
For the racks, the crossbars sit nice and low, about 3/4" off the roof at the lowest point.
There is about 45" if flat in the bars. When installed there is about a 48" space between the bars, 46" in the rear. The roof actually tapers in toward the rear, thats why its narrower in the back.

Would you be able to sell cross bars that aren't welded to the side rails? I purchased the RRO Roof Rails before I saw what you were selling. I'm going to need cross rails and would prefer to buy something you made. Would you be able to make something that just bolts on similar to what RRO has?
